I'd turn it, and add some 'brown' to the mix, e.g. straw, shredded paper (not glossy or colour printed) chopped up brown cardboard etc. If you have access to some chicken manure/guinea pig or rabbit droppings that will be a good activator to help decomposition.
Also a good helping of what Bob Flowerdew describes as 'recycled cider or beer' poured over it - my other half takes his responsibilities in this respect very seriously and is happy to undertake the recycling process if I include beer and/or cider with my grocery shopping.
So in brief, mix it up well, add brown/fibrous matter and an activator - cover it up again and stand well back - all that coupled with warmer weather will get it working.
Of course, there's always the chance that a tom cat or fox may have been spraying in the area ....
